TO ALL WHOM IT MAY CONCERN:

Be it known that I, DANIEL KELLOGG, of Jackson, in the county of Jackson, arid State of Michigan, have invented a new and improved Petroleum-Stove; iand I do hereby declare that the following isv a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this spccication, in which- Figure 1 is a detail section, through the line :u-x, iig. 3. i

Figure 2 is a transverse vertical section, through the line y-y, iig. 3.

Figure 3 is a horizontal section, through the line e-.z, g. 2.

-Similar letters of reference indicate corresponding parts. l

rlhis invention relates to a stove for burning petroleum or other inflammable oils or iuids, and consists of a tripod-base supporting a burner within a chamber, provided with a bottom dish -for adjusting the supply of air, a lateral damper, and a disk of radial springs, the latter being situated immediately over the iame, for aerating the same, and causing thc more perfect oxidation of its carbonaceous particles. i

In the drawings, A A. A are the legs or -tripod, screwed on to the body I3 ofthe stove. C is the top, which contains and supports thestove-plate D, or any vessel that occupies its place. I-beubodyl has an inner wall,

E, which is provided with deep vertical notches F, which serve as air-ports to the damper-ring G, that surrounds it, with movable contact. The damper-ring G is .provided with vertical slots, which, when brought into coincidence with the notches F, or turned oil' from said coincidence, operate as a damper for regulating thc supply of air to ther ilame. Air is admitted also from the bottom in a manner to be described, but the supply passing in laterally through the damper just described, is more or less heated, from its passage between the Walls ofthe stove, and therefore facilitates combustion of `the flame, which is spread out to meet it by a device to be described.

A hemispherieal dish, II, is placed at the bottom of the stove. It is a separate part, and is upheld in more or less proximity to the bottom of the body B, by arms L and screws ft; the said screws working in the rim of the body B, as shown at g. l, the arms i being fastened to the said dish H. The cavity of this dish serves to accommodate the bent portion of the oil-pipe J, as shown, and at the same time to catch any waste oil that may fall from the burner, while its vertical adjustability tothe bottom of thestove constitutes it a.

damper, to regulate the supply of air to the burner, which the bent pipe terminates in. The pipe .I conveys the petroleum from a reservoir, somewhere above the end, shown at I, iig. 2. This pipe passes. through a slot in the exterior wall of the'vbody B, and along and over thc-:centre ofthe stove, turning downward into the dish Iii, as shown, and terminates in a cap or burner, in top of which is a small orifice for the escape of the petra'- leum or other gas, made from inflammable fluid, by any generating-attachment now'in use. This attachment is not shown or claimed. y

To accomplish the more perfect combustion of the petroleum, a dislgK, provided with radial helical wings, is placed over the circular opening in the bottom of the body B. In this position it is immediately over` the burner 6. The oilice of this disk is to spread the gaseous dame over the bottom surface of the vessel to be heated, when the latter i's in place on the top C, and also to facilitate themore perfect combustion of the petroleum, as well as to obviate the unpleasant hissing noise peculiar to other gas-stoves- This disk, then, serves these purposes by being hung loosely on a central pivot, which permits it to revolve when .encountering the vupward draught of air from below, in a manner identical to the revolving draught-wheels placed in the walls of rooms. By this revolution the flame is spread over an increased' surface, and thus mechanically mingled with the heated air entering through the aforesaid notches F, whereby the complete oxidation or combustion ot the flame results, andthe aforesaid hissing` noise is obviated. The disk is pivoted to a thimble, d, which slides with easy contact on a rod, e, passing horizontally across the chamber of the stove, as shown. This rod is provided with supports dat its ends, exterier to the damper-ring G. These supports have hollow threads ont in their perpendicular parts to receive the screw-ends of the rod c, whereby a lateral adjustment of the rod is obtained by turning the same to the left or right, as may be, which, by means of a pin, n, on the said rod,

near its middle point, moves 4the thimble d to which the disk is attached, and thereby adjusts the latter to the centre of the llame. l

The rod is raised by means of two screws, m m, the ends of which fit into holes in the bases of the supports z', as shown at fig. 1. vThus the rod c is raised, and the disk adjusted to that height above the iame which is found by trial to give the best results. The extremities of the screw-rod c pass through angular plates z,which rest upon slotted plates p. Screws r1' pass through "the slots in the 'plates p, and prevent saidplatos from,A

rising, while longitudinal motion of the plates is permitted. Elevating screws, m,.pass through slots in "the bottom of the body B ofthe stove, and through the plates p, directly underneath the angular supports z'. vBy this arrangement the rod c, and with it the disk K, may be adjusted both vertically and laterally. Openings o, in the wall and damper-ring, provide for such lateral movement.

A slot, q, in the bottom of the body B, and extending into the circular opening P, permits the insertion and withdrawal of the pipe. This pipe is furnished with a stop-cock, S, for graduating the supply ot'uoil, or shutting the same completely off. The -said pipe rests in a notch in the exterior wall of the body B, and passing down through the slot q, before described, rests-with its bent-part in the dish H, as shown at iig. 2. To further securc the same p'ipe, an arm, M, having a ratchet part, N, is secured to the bottom of the stove, as shown at iigs. 2 and 3. A lateral notch, l, in the vertical part N, receives the pipe, and a clamp, L, embracing the pipe ,and the upper part N, holds thc former firmly in place.

When the stove is to be put in operation, the stop-cock S is turned to admit a small quantitytof theinflammable oil, which is lit at the burner. The revolving disk which was slid aside to light thc iiame is non' brought back in contact with its pin on the rod. The. plate D is replaced, a draught is formed, which causes the disk to revolve, and the heat increasing, a greater supply of oil is admitted, the dish H is adjusted, andr the stove left to burn without further care. v

The advantages of this stove consist, first, in its perfect combustion of the oil or inia'lnuiableiiuids;v second, its economical operation; third, its simplicity and durability.

I claim as new, and desire to secure by Letters Patentl. The employment of a revolving disk, substantially as shown and described, for the purpose of spread-' ing the ame of a gas or oil-stove, all as set forth. r v

Y 2. The adjustable dish H, in combination with the burner b and disk K, substantially as and for the purpose shown and described. I l i p' 3. The rod e, and elevating-screws m m, for adjusting the height of the disk above the burner, substantially as shown and described. l v

4. Providing the rod e with a screw-thread or other equivalent device, for the lateral adjustment of the, disk, substantially as and for the purpose shown and described. Y v i 5. The ring-damper G, in combination nith the disk K, substantially as shown and described, andfor the purpose specified.
